SHINGLE MIXING MACHINE Filed March 51. 1950 s Sheets-Sheet a Patented Nov. 8, 1932 PATENT OFFICE ALBERT E. F. MOONE, OF CHICAGO, ILLINOIS SHINGLE MIXING 'MACHIN E Application filed March 31, 1930. Serial No. 44.0,608.

It is frequently desirable to make patterns upon roofs by causing shingles of contrasting colors to appear in some regular order, while on others it is desirable so to break up the color or surfaces, or change the shapes as to prevent any regularity in pattern of color or design. I

The purpose of my machineis soto place shingles in the bundle or bale that the above results are achieved automatically, and, accordingly, to minimize the degree of manual handling which is required under present methods. I i

It is my purpose also to provide a machine which is capable ofmixing shingles of siinilar characteristics but of different color or surface or shape, and stacking them into bundles, so that when the shingles are taken from the bundle'in sequence and laid upon a roof, variegations in color, entirenon-uniformity', or definite patterns are assured.

I find it also convenient to design the machine in a portable form so that it may be carried to shingle stacksin the warehouse or mixing floor, obviating the necessity for transporting shingles about the plant.

These and other objects of the invention will become apparent from the following disclosure and the accompanying drawings, in which I I Fig. l is a plan view of my improved shin; gle mixing devicewith duplicated sections omitted; I I

Fig. 1 is a sectional elevation through one of the mixing units;

Fig. 5 is a detail elevation of the table rais ing and lowering structure; and

Fig. 6 illustrates an asphaltic shingle such as is used in conjunction with the device.

The machine comprises five organizations. Briefly the organizations are as follows:

1. Apparatus and means for forcing the individual shingles out of the separate uniform stacks v 2. Apparatus and means for determining what, how many and when the shingles shall be forced out from the separate stacks.

3. Apparatus for carrying the shingles away after their delivery from the individual stacks,"for maintainingthe sequence of such delivery.

4. Apparatus for stacking the shingles in bundles in the sequence as delivered by the carrier. I

5. Apparatus to prevent the somewhat sticky asphalt shingles from sticking and jamming.

Each of these functions performed by the five organizations bears a timed and sequential relation to the others.

It is to be understood that the machine may handle sheet material of any description, and accordingly the word shingle will be used throughout this specification to indicate such sheet material generically and is not confined to the conventional roofing element of the name.

With reference to Fig. 2, the apparatus comprises a base 11, mounted upon any necessary number ofcasters 10 and a table-like structure 12 supporting the various subassemblies and the longitudinal shaft 13,

which is the main driving means; Mounted upon the base 11 is a 'driving'motor 14, deliv ering power to a double sprocketj15 through the double chains 16, 16 (Fig.

The structure 12 supports an outrigger 17, upon which aresupported pillow blocks 18, '19, 20, etc., providing bearing for the main shaft 13. Supported by the structure 12 is a series of slotted tables 21, 21, etc. It is to be understood that two elements only of the machine are shown and described. The other shingle releasing mechanisms are duplicates of those described, and may exist in any number which the pattern to be produced, or the number of colors to be mixed, demands. In

the case of the specific machine disclosed in the invention there are five such units.

The shingles to be mixed are placed in the form of stacks on tables 21. Such stacks are indicated at 22, 22. The shingles. are held in position against forward displacement (to the left with reference to Fig. 2) by stop assemblies 23, 23, carried by the structure 12. The assemblies, as shown in Fig. 4, comprise a series of flat bars 24, 25, 26 and 27, making a rectangular frame with braces 28, 28, also attached to the part 12. From the bar 25 hang a plurality of stop members 29, which are hinged at 31, 31. The bar 27 is pierced to allow bolts 32, rigidly attached to the stop members 29, 29, to pass through. The bolts are provided with springs 33, working against the bar 27 and the cap of the bolt. The stop member 29, therefore, is normally pulled into engagement with the bar 27. The stops may be regulated for height by means of the adjusting screws 34, 34.

The main drive shaft 13 is provided at 44, 44, with bevel pinions which mesh with driven bevel gears 45, 45, mounted upon the transverse shafts 46, 46 (best shown in Fig. 4). The shafts 46 carry a seriesof sprockets 47, 47, etc., over which small carrier chains 48, 48, run, which work over sprockets 49, 49, rearwardly positioned behind the stack of shingles. Each of the carrier chain sprockets 49 is individually adjustable for tension upon the chain, as shown in Fig. 3. As indicated in Fig. 3, the sprockets 49 are carried on a bracket 51, slidable upon one of the components of the support 12, and ad justable for tension by means of the cap screw 52 and the locking means provided.

Each of the chains 48 carries a small engaging block 53, projecting upward through the slots provided in the table 21, the purpose of the blocks 53 being to engage the rear edge of one or more of the shingles 22. Two of such blocks are positioned in the whole length of the chain, so that two shingles are engaged and ejected for each complete revolution of the chain. The hinged stop members 29 prevent the whole stack of shingles from moving ahead when the chains force the engaging blocks 53 into contact with the shingle. The height of the stop 29, however, is adjusted to allow one, two or three shingles to pass out below it. Such is the mechanism for forcing shingles out of the stack.

The mechanism determining when and how many shingles are to be released is as follows :The table 21 is raised or lowered automatically. Two brackets 54 and 55 are provided with slotted ends in which cap screws or rivets 56, 56, rigidly attached to the table 21, are free to move in a vertical direction only. The table is supported by connecting link members 57, 58, in which turn buckles 59,61, are provided to allow initial leveling of the table. The lower extremities of the link members 57, 58, are con nected to hell cranks 62, 63, carried by cross shafts 64, 65. The bell cranks are connected by an intermediate link 66 in such a way that when the shaft 64 is revolved in a clockwise direction the shaft 65 will revolve in a countel-clockwise direction and the table 21 will rise to a degree determined by the angle through which the shaft 64 is rotated.

Below each of the shingle units are located cams 67, 67, carried by cross shafts 68. Qhe cams are carried on the faces of large sprockets 69, also mounted upon the same shaft. The contour of the cams 67 may be changed by the insertion of blocks 60, 70, etc. Each block occupies one-fifth of the circumference of the cam and determine the elevation of the roller 72. The arm 71, projecting from the shaft 64 and rigidly a 'tached thereto, carries the roller 72 at its further ere tremity, which engages with the face of he cam 67 in such a way that upon the rotation of the cam the shaft is caused to revolve clockwise and counterclockwise through a part of one revolution.

For the purpose of providing drives to the cams and for assuring the proper timed relation for the cooperation of the parts, the shafts 46 carry small sprockets 73, which deliver, through the chains 74, power to the sprockets 75, 75, mounted on the cross shaft 76. concentrically mounted with the sprockets 75 are smaller sprockets 77, 77, which deliver power, through chains 78, 78, to the sprockets 69. The ratio of the gears 44, 45, the size of the sprockets 73, 75, 77 and 69, the speed of the motor, and the reduction obtained by the primary drive, are all chosen to secure proper correlation of movement in the apparatus.

A conveyor system formed of a series of chains runs from the rear to the front of the machine carrying shingles to the front. This conveyor is composed of chains 35, 35, etc, working over the sprocktts 36, 37, which are supported by the shafts 38, 39, journalcd in pillow blocks 41, 42, mounted upon the base 11. A series of longitudinal hardwood bars 4.3, 43, etc., lie directly beneath the chains affording them support.

The cam 83 carries upon its face a complex slot 93, in which rides a pin 94, attached to the arm which is pivoted at a point 9 and at its further extremity 97 also pivoted to the vertical rack 98. hen the cam 83 revolves, therefore, the rack 98 is driven up and down. The rack 98 engages with a gear mounted upon a transverse shaft 101. so that vertical movement of the rack causes the sh to revolve. The rack is kept in engagement with the gear 99 by means of the yoke 102 and a roller 103 carried by the yoke. The shaft 101 carries a series of right an le shaped arms 104, 104, placed intermediatelv between the carrier chains 35, as illustrated. When the cam 83 revolves, therefore, the intermediate linkage will cause the right arms to pick up whatever shingles nay been carried to them by the carrier ch swing them through 180 of are, and drop them upon the roller carrier 105. Carrier chains -are driven through the intermedi ary of a sprocket 106, located upon the shaft 76, and a connecting chain 107 driving the sprocket 108, mounted upon the shaft 39. The cam 83 is carried upon a short jack shaft 109, upon which is mounted a sprocket 111, which is driven through the chain 112 by a sprocket 113 located upon the shaft 76.

The organization for preventing the shingles from sticking and jamming is as follows A crank 81, pivoted at 79 upon an upwardly extending portion of the support 12, carries at its extremity a roller 82, which bears upon the face of a cam '83. The upper end of the crank is pivoted at 84 to a lon itudinal bar 85. Azlike bar 88, carried on t e pivoted supporting members 80, 80, is located at the other side of the machine.

Extending between these two parallel bars, and located immediately in front of the stop members 23, is a series of cross rods 87,'Which are afiixed to the parallel bars. The cross rods carry in their length a series of hammers 86, which engage with the flexible members 29 of the stop system. Since the bars are free to swing slightly horizontally, the hammers hit the spring stop members 29 whenever the sharp projection 92 ofthe cam 83 passes under the roller 82. The stop bars 29 are-immediately restored to their proper position by the pull of the spring 33 exerted against the stop frame element-27 and the cap of the bolt 32, which is attached to the hinged stop bar.

The operation of the device is as follows The revolution of the shaft 13 causes, through the appropriate driving intermediaries, the engaging blocks 53 to be forced forwardly through the. slots in the table 21. The block 53, therefore, causes the bottom shingle of the bundle 22 to be forced out from under the stop member 29. The revolution of theappropriate cross shafts 76, 68, etc., causes the cam-67 to revolve and the arm 71 to move upand down following the contour of the cam. For each one-half revolution of the chain carrying the engaging blocks 53, the cam 67 turns. through one-fifth of a revolution. Accordingly, through the appropriate mechanism, the table raising and lowering shaft 64 is turned, and the table linked thereto is raised or lowered depending upon the particular block 60, 70, etc, which is presented by the cam face atthe time.

In the organization of the machine as de' scribed, when the table is dropped to its lowestpossible position and the stop member 29 is raised to its highest adjustment, three shingles may be forced out from under the stop 29. As illustrated in'Fig. 2, the block applied to the cam face will allow no shingles to be forced out from under. Block will allow one, shingle to be forced out and the space 114 on the cam face, which is unpro vided with a block, allows three shingles to be forced out onto the carrier. chains 35 then receive the shingles which drop onto them from above. .These chains are in continuous movement throughout the operation of the machine. The shingles then bring up against the part 115 of the throwover arms 104. The arms, as before described, are forced through pickingup the shingles from the chains 35 and dropping them on the roller conveyor 105. The shingles are deposited upon the conveyor with the under surface, as the shingles lie upon the chains, uppermost. a

Thefunction of the arms 81, thehammers 86, and the-hinged stop member 31, etc, is as follows :,As the cam 83 revolves the sharp projection 92 hits the roller 82, causing the arm .81 to be thrustbackward violently. The hammers 86 then strike a sharp blow on the stop members 29, which may yield slightly, and are instantly retracted to their normal position by the springs 32, pulling them against the stop bar 27. The stack of shingles, therefore, receives a considerablejolt before the next shingle is to be thrust fort-h. Sticking or jamming under the gate isaccordingly obviated.

It is understood that the positioning of the blocks applied to the face of the cam67 is the Controlling factor in the shingle mixing machine, and that since all operations occur in timed relation unit 1 may depositnone, one, two or three shingles of one color upon the carrier; unit 2-may deposit three, two, one

or no shinglesof a different color upon the carrier; units 3, 4i and5will duplicate the performance. The stack ofmixed shingles which is built up uponthe carrier 105, therefore, will contain as desired shingles of vari- The carrier ous colors in color sequence, or groups of shingles of the same color, up to three, which is then broken bysome other color. If five units. comprise my machine it may be seen that the variegation of color, or the multiplicity of patterns which my machine will produce, is in excess of two hundred difierent combinations.
